Many streams have distinct vegetation zonation, but few have quantified the time it takes to recover or reestablish those vegetation types once they are disturbed. How quickly or slowly a species responds to a disturbance can inform one of the age of past disturbances. Knowing the level at which aquatic mosses and lichens occur is helpful for determining the elevation at which to build infrastructure such as bridges or trails along a stream. Streamside zonation can be used to indicate disturbance levels or modifications to systems while also aiding in determining high water marks or calculating river channel capacity and flood frequency. We found that the aquatic mosses and lichens were relatively slow to reestablish. After 27 years, there were very little changes.
